Caching Patterns

Strategies and implementation patterns for application-level, distributed, and HTTP caching.

When to Activate

• Adding Redis or Memcached to reduce database load or API latency
• Designing TTL values and cache invalidation strategies
• Preventing cache stampede on high-traffic keys
• Configuring HTTP Cache-Control and CDN caching rules
• Choosing between cache-aside, write-through, or write-behind
• Debugging stale data, cache poisoning, or thundering herd problems
• Sizing a cache or deciding what to cache vs. not cache
